SPINNING ND TWISTING SPINDLE.

Specification of Letters Patent.

vIatented May 12, 1908.

To all whom 'it may concern:

Be it known that we, VALoRUs S. WEST- ooTT and GEORGE B. ALLEN, citizens of the United States, and residing at Iawtucket, in the county of Providence and State'of Rhode Island, have invented certain new and useful Im rovements in Spinning and Twisting Spin es, of which the following is a slpeciiication.

y he present invention relates to spinning In devices of this character the rotating spindle is stepped into a non-rotary bolster which is sup orted near its upper end and'made smaller 1n diameter along its length than the containing case, so'

that under inequalities of the yarn load on the `bobbin carried bythe spindle which tends to vibrate or gyrate the spindle, the latter will be allowed to find its own center of rotation.

Various means have heretofore been lemployled to cushion the spindle and confine it wit in certain limits so as to reduce or remove the liability of vibration and wear when the spindle is slightly out of balance or using an untrue bobbin. in the art prior to our invention, so far as we are aware, employs a spring which yieldingly holds the bolster in the position to which the spindle may shift it. These means, however, have' proved either inefficient for 'high speeds or are expensive to make.

The ob'ect of our invention is to provide a novel an peculiarly simple construction of s indle of t e gravity type whereby the spint e will center itself with promptness and certainty, and in which any undesirable movement due to an unbalanced load or other disturbing tendency will be effectively controlled, and-consequently the attainable rate of 'spindle rotation materially increased. This we accomplish by the employment of one or more annular members or tubes held in a fluid containing reservoir, said tubes being dis osed relatively to each other and to the bo ster and bolster case as to -provide a series of thin annular spaces for the liiuid, forming thereby in a small space a comparatively large cushioning surface to counteract the vibratory or other disturbing tendencies and at the same time allowing the bolster to yield gently under such force as maytend to move it laterally.

The invention will be understood by reference to the accompanyin drawings in which Figure 1 is a vertical ongitudinal section The latest advancel of one embodiment of our invention, certain of the parts bein in elevation; Fig. 2 a vertical sections to illustrate various `modificah tions ,and Fig. 11 a horizontal section showing corrugated tubes.

Similar reference numerals indicate siml- `lar parts in the several views.

-upper section 4. A nut 8 engages the threaded section of the case and is adapted to clamp the latter to the rail `of the spinning frame in the usual manner. The section 4 of the case extends within the whirl 2 and the upper edge 9 lthereof constitutes a seat for a shoulder 10 formed on the upper end of the bolster 3. To prevent any rotary movement of the latter it is provided with a key 11 (see Fig. 3) engaging a groove 12 extending longitudinally'of the inner wall of section 4 of the case. The case is bored to permit of a slight lateral play of the bolster 3, and the latter is bored to a sulicient depth to pro- .vide a proper bearing for the rotating spindle. Asshown in Fig. 1 the bolster is bored throughout its length the lower opening thereof receiving and being closed by a dependingpin 13 which projects for a substantial distance into the lower section 5 of the case. For` a short distance above said pin the walls of the bolster are constricted to provide a seat 14 for'the lower end ofspindle 1. The detachable section 5 of the bolsterA case constitutes aluid4 reservoir, the fluid bein fed from the usual well 15 formed in the ange 16 'of the section 4 of the case, through ducts 17. In the construction illustrated in Fig. 1 the bottom of section 5 lower end of bolster 3 into the oil reservoir. Resting loosely upon the bottom of the reservoir is an outer cylindrical tube 21 which extends upwardly to encircle the tube 20. In practice the-lengths of the tubes 19, 20 and 21 relatively to each other are substantially as shown in Fig. 1. These tubes may be of any suitable material, preferably metal, the walls'of which are from one-sixty-fourth to one-thirty-second of an inch in thickness. They are spaced apart, and the inner one 19 from pin 13 to admit a thin film of iuidbetween the o posing walls. The uid used by us is that linown to the trade as spindle" oil, although any other suitable material for cushioning and lubricating may be em-I` ployed.A itable ducts 22 are provided to admit oil to the spindle bearing in bolster 3.

In Fig. j 5 the bolster 23 is not bored throughout its length as in Fi 1, the lower part thereof being solid and formed with a narrowed portion 24 projecting into the reservoir of section 5 of the case. Secured to the body portion of the bolster 23 is a depending cylindrical tube 25 between which and the projecting end 24 of said bolster is a cylin* drical tube 26. The latter is seated on a perforated wall 27 extending across the lower art of section 5 to provide a sediment chamer 28.

Fig. 6 illustrates an embodiment of the invention similar to that of Fig. 5 except that in the former the outer cylindrical tube 25 is omitted. The use of a single tube, while productive of satisfactory results, we believe to be not as eil'icient as the use of two or more tubes.

F ig. 7 illustrates still another method of disposing of the tubes. In this form the depending tube 25 is the same as that of Fig. 5. This projects downwardly between the two legs of a U-shaped piece, said legs 29 and 3() constituting in reality two tubes joined at their bases and resting on the bottom of the oil reservoir. In this instance a pin 31 is stepped into an opening in the bottom of section 5 ofthe cas'e and serves as a lateral support for the inner member 30. The diameter of pin 32 which' pro'eets from the lower end of the bolster 33 is slightly less than that of pin 31 to provide an annular space between the former and the member 30.

Fig. 8 illustrates an embodiment of the invention in which the tubes 34, 35 and 36 are so disposed as to encircle the pin 37 dep-endin from the bolster 33 into lthe oil reservoir. Al these tubes are unattached and rest loosely upon the bottom of section 5 of the case.

In Fig. 9 the bolster case 38 is shown as made of a single castino` instead of in sections as heretofore described. The disposition of ,the tubes 25 and 26 is substantially the same as illustrated in Fig. 5. A shouldered pin 39 isv set intouthe lower end of bolster 3.

In Fig. 10 the bolster 40 is modified by having its lower end recessed for a substantial distance to constitute a tubular member 41. In this form two tubes 42 and 43 rest loosely upon the perforated plate 27, and extending into the space between said tubes is a tube 44 secured to bolster 40. A pin 45 is stepped into the bottom of section 5 of the case and projects upwardly into the tubular member 41.

Although we have shown the tubes as having plain surfaces they may be corrugated as shown in Fig. 11. l

-In all forms of our invention above de' scribed it will be observed that the bolster is freely sus )ended at its upper end and has free latera play from its pomt of suspension. lt results from this that any force acting on spindle 1 tending to disturb its condition ol' equilibrium is transmitted to the bolster and this force is cushioned by the mobile ilm oloil or other fluid interposed between the bolster and the next immediately' encircling tube, and so to the film of fluid between the inner and the next encircling tube. 'lhe iiuid has free access to the annular space between the tubes and its nature constitutes it an ellicient cushioning agent to minimize the effects of the vibratory or gyratory movements of the spindle. By the employment of a series of concentrically.disposed tubes the slightest movement imparted to the bolster by the spindle is instant-ly resisted by and distributed to and over the comparatively large surface area of the film of fluid inter osed between contiguous tubes, the result eing to reestablish the normal workingI high speed equilibrium of the spindle in a much more sensitive, rapid and easy manner than has heretofore been attained.

By means of our invention any tendency of the spindle to shift or move the bolster laterally in response to the movement of the former to vconfine its axis ol' rotation in line with the center of gravity when carrying an unbalanced load is immediately and automatically corrected, this being effected before such movement becomes detrimental to an extent sullicient to break the yarn orI lift the bobbin from its seat.

In the foregoing specification we have referred to an oil chamber and to oil as the shown.

What we claim and desire to'secure by Letters Patent is 1. .Ina device of the characterndeseribed the combination of a bolster case having a liuid containing reservoir, a `bolster freely suspended at its upper end in said case, said bolster having free lateral play from its point of suspension and extending into said reservoir, a spindle supported in said bolster, and a plurality of concentric tubes-disposed in said reservoir and encircling the lower end of the bolster to form thin mobile cushioning walls for the purpose described, one of said tubes being secured to and depending from `the bolster.

2. In a device of the character described the combination of a bolster casehaving a fluid-containing reservoir, 'a bolster freely sus e ed in said case and extending into sai( reservoir, a spindle supported in said bolster, and a lurality of annular members dis osed in sai reservoir encircling the lower enr, of the bolster to form thin mobile cushioning walls for the purpose described, one of said annular members depending from the bolster.

3. In a device of the character described thecombination oi a bolster case having a fluid-containing reservoir, a bolster freely sus ended in said oase and extending into sai reservoir, a s indle supported in said reservoir, and a p urality oi annular members disposed in said case to form thin mobile cushioning walls, the lower end of the bolster constituting one of said members.
